The program can set locktime to an actual time or to the block height. Adding a locktime to the script means that the transaction will only be confirmed and the new block added once the requisite time has elapsed or the block height has been met. Put another way, when a this function is added to the script, the transaction is not valid until the set time or height.

You can think of locktime being like a post-dated cheque; the cheque is not processed until the named date. Transactions with locktimes are therefore rejected until the specific time or height set by the script is reached. It is also the last field in the script, which you can see below. Most transactions do not use a set locktime. Below is a Bitcoin transaction. Note that the last list of is the locktime.

Note also that if the locktime was disabled, the default remains which looks like this: 0xffffffff. Locktimes are useful in the event that the signer s decides to change their mind. In the case that a signer does not agree to the transaction, they can instead add a new non-locktime transaction. The new transaction will use one of the same outputs from the inputs.

The input is derived from what was originally an input from the locktimed transaction. These transactions are invalid until the time set in the script, so long as the new transaction is added to the blockchain before the time lock expires. This is an important caveat to remember with locktimes. Locktimes are related to block time, which is the average time it takes to generate an extra block in the blockchain. Block time, however, can be up to two hours ahead of real time.

Moreover, blocks are not created at specific intervals. This means that there is no precise measurement to know exactly when a block is added. It is therefore important that if the signatory wants to invalidate the transaction they do so as much in advance of the locktime as possible. Because of the way time operates in the Bitcoin blockchain, it is very possible that a node will approve the transaction two hours earlier than the time written into the script even if it has a time set.

There are two ways to set a locktime, using block height or a specific time. Unix Time is a measurement of time used to describe a point in time. Every day is measured in seconds and is counted as if the day contains exactly seconds. Locktime can be set to make sure that a transaction is locked until a specific block height or a point in time. So the locktime has a dual-function by setting either a block height or time.

The ability to disable locktime was not an original feature. However, setting all sequence numbers to the default 0xffffffff can still disable the time lock. I'll let you know about cool website updates , or if something seriously interesting happens in bitcoin. Don't worry, it doesn't happen very often. Locktime sets the earliest time a transaction can be mined in to a block.

Usage You can use locktime to make sure that a transaction is locked until a specific block height , or a point in time. Examples Most transactions do not make use of locktime, so their locktime is set to 0x Nonetheless: Locktime Decimal Description 0xede This transaction could only be relayed on the network after the blockchain reached a height of , The transaction could only be relayed on the network after the median time of the last 11 blocks according to the time field in their block headers is greater than this.

This is effectively like setting the locktime to 0x , as the first ever block was mined on 02 Feb The current unix time is 1,,, also known as 15 April , , which is already above ,, Hey there, it's Greg. This transaction could only be relayed on the network after the blockchain reached a height of ,

This functionality is useful for other constructions such as HTLCs, but not for ensuring that the current on-chain funds don't get spent. You can learn all about the different types of time locks in this post by James Prestwich:. One problem with simply applying them to Casa accounts is that it breaks a fundamental aspect of our security model that results from our seedless setup - the flexibility to rotate keys for compromised devices.

Could we only time lock a few keys? OR we could envision a script where the available signing keys change in a multi-step manner, from 3-of-5 to 3-of-6 to 3-of OR you could go the other direction, where the number of signatures required decreases over time, from 3-of-5 to 2-of-5 to 1-of Thus, in order for you to have a script that can handle a variety of situations with what is effectively different time locks on different keys, the complexity and number of conditionals in the script will blow up rather quickly.

This is bad for both the on-chain transaction fees and for the privacy of wallet users, as these scripts will be fairly unique and thus fingerprintable. Though we need to be especially careful about designing more complex scripts because we are effectively changing the security model! In each Casa multisig keyset, one is secured by Casa for use in emergencies , and most keysets contain one Mobile Key essentially a "hot" key.

More complex scripts for degrading multisig may require a lot of additional logic in our application regarding which devices are allowed to spend from which UTXOs. For simplicity and sanity, it may be preferable to require ALL UTXOs in a wallet to be encumbered by the same lock time and same public keys. As mentioned earlier, there are also privacy and transaction fee ramifications since every UTXO will now need to be protected by these more complex scripts, even if the time locking functionality never gets executed.

It will also make the guide for Sovereign Recovery guides we provide our clients for recovering their funds using open source software, in case anything were to happen to Casa far more complicated. It would no longer be possible for us to hand the user a single PDF with recovery data because the data would no longer be deterministic.

This is because the redeem scripts would no longer be standard, but would instead contain dynamic data - the timelock values. Most likely the latter. This would further reduce the sovereignty of Casa users and increase their reliance upon our software. Taproot uses Merkelized Abstract Syntax Trees to partition the execution of complex Bitcoin scripts so that you only need to reveal the branches that get executed. In the "normal" case, you'll never even need to reveal any of the unused complex logic.

On-chain it will just look like a single signature transaction was executed via the use of aggregated Schnorr signatures. We could then lock funds in such a way that, under most conditions, the spend will only look like a single signature spend on the blockchain, even though it is actually a multi-signature scheme behind the scenes. But in the case where keys have been lost, we would conditionally execute and expose only the logical branches that are necessary.

However, this still leaves the Casa-less wallet recovery issue due to the creation of complex, nonstandard nondeterministic redeem scripts. To learn more about the issues arising from creating Bitcoin scripts that contain nondeterministic data, check out my keynote at the MIT Bitcoin Expo earlier this year:. As wallet developers begin to take advantage of more complex scripting with Taproot, I expect we'll need to develop new standards for how to describe the scripts that might be used to encumber funds in a given wallet.

Then, hopefully we can devise templates that enable the recovery of complex wallets via a discovery process that is similar to how address derivation works today, simply with additional variables. For example, if there were an ECDSA or RIPEMD algorithm break that made any coins spendable with a few months of CPU time, the network might need to to prohibit moving old unspent coins after some transition, but long locktimed coins could not make such a transition.

Occasionally coins have been accidentally locked up for a long time. Jump to: navigation , search. Category : Technical. Hidden category: Pages needing citations.
